Determining biometric data using an array of infrared illuminators
Methods, devices, and systems related to determining biometric data using an array of infrared (IR) illuminators are described. In an example, a method can include projecting a number of IR dots on a user using a dot projector and an array of IR illuminators, capturing an IR image of the number of IR dots using an IR camera, comparing a number of pixels of the captured IR image to a number of corresponding pixels of a baseline IR image using a processing resource, and determining biometric data of the user at least partially based on comparing the captured IR image to the baseline IR image using the processing resource.

Artificial intelligence (AI) procedure for normalizing thermal skin temperature to body temperature
Methods, systems, and devices for data processing and artificial intelligence (AI) techniques are described. A system may support person detection using an optical camera and temperature detection using a thermal sensor. The thermal sensor may determine a temperature reading corresponding to a tracker for a specific detected person. A processing device may update a current temperature for the tracker based on the temperature reading and may add the updated current temperature to a baseline. For example, the processing device may use AI techniques to manage one or more baselines supporting handling of differences and changes in ambient temperatures. The processing device may determine that the current temperature for the tracker satisfies an alert threshold and may trigger an alert procedure. For example, the processing device may use an active baseline to correct the current temperature from a skin temperature to a body temperature for comparison to a fever detection threshold.

Systems and methods to protect the health of occupants of a vehicle
This disclosure is generally directed to systems and methods for protecting the health of occupants of a vehicle. In an example method, a health monitoring apparatus in a vehicle evaluates an individual and detects a symptom of a contagious disease. The individual may be already seated in a first seat in the vehicle or intends to enter the vehicle. The health monitoring apparatus identifies a second seat that has a pre-defined spatial separation distance from the first seat. The pre-defined spatial separation distance can exceed a threshold spatial separation distance selected to provide health protection against the contagious disease. The health monitoring apparatus issues an advisory to the individual to occupy the second seat. In another example method, the health monitoring apparatus may adjust an airflow pattern in the vehicle so as to provide directional airflows to protect various occupants of the vehicle against an airborne contagious disease.
PRESENTATION ATTACK DETECTION
An apparatus for capturing an image of an object on a platen and including a platen having a surface for receiving the object, wherein the platen is transmissive to an optical wavelength of light, an illumination module configured to illuminate at least a portion of the object with light from an illumination source, and an optical sensing module configured to receive the light from the illumination source after the light interacts with the at least a portion of the object. The light from the illumination source is spatially patterned prior to reaching the object. The illumination module can be configured to create the spatially patterned illumination and/or the platen may include a patterned optical coating creating the spatially patterned illumination. The spatially patterned illumination can include a plurality of discrete areas (e.g., a stepped pattern) of different illumination intensity and/or a gradient of different illumination intensity.
